To {zZ/ wko/a, it may concern y lle it known Ithat. NESIME E. MICHAUD, a citizen of the United States, and a resident of the city of St. Louis and State of Mis souri, have invented a new and useful improvement in RollersBearings, of which the following` is a specication.

This invention relates to roll carrying and spacing devices for conical roller bearings. A

'llhe object of the invention is an improved vcombined roll carrier and spacing device which can be readily assembled with the rolls and hearing ring, and which may be as readily disassembled, if need be.

The invention consists in a rollspacing cage `which increases in diameter toward one end approximately in proportion to the in crease in diameter of the tapered rolls, and which carries a roll retaining ringl at each end interloclied Jheren/ith.

vlurther objects of the invention appear below in connection with the description of the embodiments thereof illustrated in the accompanying drawings,A and in what the 'invention consists is particularly pointed ont in the appended claims.

In the drawings, in whighlike characters reier to the saine parts thigaighoui. ehe several views, 1Figure l is an axial sectional View of a roller hearing en'ibcaiyng niv invention, on the line l-l in Fig. 2; Fig. E2 ie a transverse .sectional view of the saine on the line 2--2 in Fig. l; Fig. 3 is an end vieafA o' the spacing cage; Fig. e is a side View of the saine; Fig. 5 is a hroadside view of the split locking ring; Fig. (i is a broadside Viewv of the outer retaining ring; Fig. i is a sectional v'ew of the saine on the line 7-7 in'llig. 6; Fig. 8 is a broadside vien' or' the inner retaining ring; Fig'. 9 is a SideA elevation or' the saine on i'he line 5)-9 in Fig. 8; Figs. l0 to 13, inclusive, are views similar to Figs. 6 to 9, inclusive, showing modified forms of retaining rings; and Fig. 14 is a part sectional View of a fragment of a spacing cagmshowing a means for securing the ends of the split locking ring.

Rererrino "so `the drawins,the bearing shown in liigs. l and 2 comprises a conical inner race ring 2l havin" a shoulder or rib .22 around its larger ein., tapered rolls Q3 spaced'circunii'ercnlialiy around said ring and adapted to roll thereon, with their axes intersecting the axis oi the ring .at a com-- nien point, and a cylindrical enter ring 24C having a4 conical inner raceway within which the rolls 28 hai-'etheir bearing.

` A spacing cage 25, having a tapering form corresponding .to the inclination of the axes of the rolls, is arranged hein-'een the inner and outer roll raceways. This cage is formed with lengthwise openings 26 spaced around its periphery. These openings have walls which are parallel in the direction of their thickness and which contorni in outline to the outline or' the hearing portion of the rolls, whereby the rolls may bevassenibled therein by inserting' them from either within or without the cage.

The larger..end of the' cage has an outer circumferential flange QT, and the outer periphery of the cage immediately adjacent, thereto is cylindrical, forming a seat for the larger retaining ring 2i). The larger retaining ring- 29 is slidahle onto the scat 28 from thesnialler end of the cage, 'out the inward projecting ears 30 prevent rotation thereof on the seat. These ears 30 project into the openings 2G in the cage and engage'hetween the side walls thereof at the larger end oi the cage. lheears are formed with circular grooves Si on their .faces toward the openings 2G to inforide seais for the pointed ends` o' the rolls.

smaller end of the caen.y with. its ears 53 proiectingV outward into the openings 2 6 and fitting between The side walls thereof at their smaller ends. The cars of thesinaller retain .i similar rc. taining` ring 32 is arranged within the.

ing' ring ha re circular grooves 3i for seating the inner ends of the rolls. A. split locking ring is arranged around the seat .28 of the cage between the ,Bange 27 and larger retaining.;.ring- 2) for preventing the end Wise movement of the latter away from the ends of the rolls. The ends 3G of the loch'- ing ring are bent inward to engage between the side walls of one of the openings QG, ther extremities of saidv ends being bent around to engage the inside oi' the-cage, as shown.

in Fig. 14.

The retaining rings 37 and 38 shown ni Figs. 10. to 13, inclusive, are like the rings 29 und 32, above described, except that the ears 39 are formed with eountersnnk holes 40 forv the ends of the rolls instead of'circiilar grooves. To assemble the rolls and cage, the retaining rings are iirst slipped the larger one over and the smaller one within t ie cage, and ositioncd with their ears projecting into t e openings 26, and touching the endstiiereo". The ooge may be slipped over the inner bearing ring or Within the enter bearing ring, and the rolls inserted in t ie openings either frein he outside er roin e 'tee 'inside7 depending on 'Whether the cage outside er inside the hearing ring race- Wav, Aifer the relis ere in place, the larger ring; 2E? le edgusted lengthwise to seem-e the ends of the relis between it end the smaller retaining rnigE and the split leekn'xg 351s snapped into the space between the retaining ring 29 and the flange 2? oi' tiie'enge. The ends of the locking ring nre 'iliade' fest, end thenfssenlibling operation is complete exceptfor inserting or eli;y ping; en the'reinziining bearing ring.

Iit also evident that the forms end sizes of the Several parte of the device shown in the drawings may be modi lient departing from the invention, :and i do noirestriei the invention to the preciee forms and shown.
